Generalized Electric Vehicle Reverse Engineering Tool
A project turn the GEVCU hardware into a specialized reverse engineering tool.
The project now builds in the Arduino IDE. So, use it to compile, send the firmware to the Arduino, and monitor serial. It all works very nicely.
You will need the following to compile this project:
- Compatible hardware such as GEVCU, CANDue (1.1 or 2.0), or EVTVDue
- Arduino IDE 1.5.4 or higher (tested all of the way up to 1.6.6)
- due_can - Object oriented canbus library for Arduino Due compatible boards.
- can_common - Common structs and functions for CAN libraries.
- MCP2515 - Facilitate CAN functionality with the onboard MCP2515 CAN controller.
- due_wire - An alternative I2C library for Due with DMA support.
- SdFat - Arduino FAT16/FAT32 Library (Note - now using Beta version!)
- DueFlashStorage DueFlashStorage saves non-volatile data for Arduino Due.
- Wire_EEPROM I2C based routines to support EEPROM on the Due.
All libraries belong in %USERPROFILE%\Documents\Arduino\libraries (Windows) or ~/Arduino/libraries (Linux/Mac). You will need to remove -master or any other postfixes. Your library folders should be named as above.
The canbus is supposed to be terminated on both ends of the bus. This should not be a problem as this firmware will be used to reverse engineer existing buses.
